How much am I worth? Help! My livelihood depends on it!?

I need money for a trip to NY this summer. I have asked my dad to start paying me to do chores. I have never gotten an allowance before. :( I am gonna be taking on all dog responsibilities such as picking up poop, feeding, watering and walking. I will be cleaning both me and my parents bathrooms and keeping both my rooms clean at all time.(I have 2 rooms cause my siblings moved out haha) So how much should I get per week? I want 15 but he says 12. :p
